Some cool new features come to Google Photos for iOS, including Portrait Mode Bokeh, editing and changing the blur focus point, as well as leaving the subject of your image in color while changing the background to black and white. As noted by the Google Photos team on Twitter, iOS users can now adjust the Bokeh wallpaper blurred after the image is taken and change the focus of the photos in portrait mode.
New to iOS, adjust Wallpaper and change the focus of your portrait mode image.
Just capture a portrait photo in Google Photos, click the edit icon to access the edit menu, and tap it again to edit depth and focus.  – Google Photos (@googlephotos) November 19, 2018
To get started, first open a portrait mode image in the Google Photos app. Then click on the edit icon to access the editing menu. Turn on the icon again to edit depth and focus
Verge tested feature and noted:
Google seems to do its own processing when moving depth control around; The results are noticeably different, in some cases better than what I get with the Apple Photos app. There are several other camera and image editors that can use deep data from iPhone to increase or decrease bokeh. Touching an area of the image to change the focus did not make a difference in a short period of time as tested this feature. Calling the blur makes it basically the same.
Another new feature of this edition of Google Photo is a new color scheme option that maintains the color as you desaturate everything else to black and white. This was previously offered as a finished effect through the Assistant section of Google Photo.
Color pickup helps you achieve the same Assistant look by manually playing with the Color Picker slider, plus you can manually do this for any portrait image you want. The new depth editor also works with portraits taken with Pixel 2, Pixel 3 and Moto phones like the Moto G6.
From now on you can get more control over your standing pictures. Use our new depth editor to adjust the background noise and change the focus of just a few cranes.

If you have the latest version of Google Photo, and this feature is not available in the app, because Google often announces features before they actually roll out. If so, you can only see the app in a few days or weeks.
Google Photos is a free download from the App Store.
